python读取图片为数组_Python中读取图片并转化为numpy.ndarray()数据的6种方式

import numpy as np

import cv2

from keras.preprocessing.image import ImageDataGenerator, array_to_img, img_to_array, load_img

from PIL import Image

import skimage.io as io

import matplotlib.pyplot as plt

import matplotlib.image as mpig

'''

方式：                        返回类型

OpenCV                        np.ndarray

PIL                           PIL.JpegImagePlugin.JpegImageFile

keras.preprocessing.image     PIL.JpegImagePlugin.JpegImageFile

Skimage.io                    np.ndarray

matplotlib.pyplot             np.ndarray

matplotlib.image              np.ndarray

'''

imagePath="E:/DataSet/test1/trainSet/bus/300.jpg"

'''

方式一：使用OpenCV

'''

img1=cv2.imread(imagePath)

print("img1:",img1.shape)
